In around 100 well-illustrated pages this very nicely produced little (15x21 cm) hardback book describes the rather troubled history of the German Wright operation and the man behind it, Friederich Karl Klose. It has lots of illustrations and is printed with big font, but I learned several new things about the company and its dealings with the difficult Wright brothers. At only EUR 13.95 I think it's very good value for money.

As far as I can tell from a quick look, the book only contains one page with brief notes about Abramowitsch's flights at the May 1912 Johannisthal "Frühjahrsflugwoche" and his July-August 1912 flight to St Petersburg.
